Ser Jorah Mormont and Jaqen H'ghar from A Song of Ice and Fire series by George R.R. Martin. It’s hard to distinguish primary and secondary characters in this series because there are just so many characters in the first place.

Alice from Twilight by Stephanie Meyer. She was such a likeable character.

Honestly, that is all I can think of right this second! But those are some of my favorites.
